Application filed Eeceinber 10, 1919.

To ZZZ whom ZZ' may concern Be it known that We, llannr HOFFMAN and Louis Hormrriiv, citizens of the United States, residing Philadelphia, county of Philadelphia, and State et Pennsylvania, have invented a newv and useful lmprovenient in lllater Connections for Automobiles, orn which the following is a full, clear, and exact lcscription, reference being had to the accompanying drawings, -which forni a part of this spe incation.

The object ot our 'nvention is to provide a con ectcn for the ends ot the Water pipes in the coo systems c Will be `flexible and adjustable and saine time of great durability.

The present method of making connection the enes of Water pipes in cooling systems is by the use of lengths oi rubber hose, Which are slipped over the ends of the pipes and clamped in place by means of clamps. Leakage is prevented by sliellacking the ends of the pipes.

rlhe present devices are open to a number ofserious objections in that the hot Water rots 'the inner lining of the hose, causing it to drop oii" and block the system, or parts of it. The action ot anti-freezing solutions greatly increases the rotting action. The internal rotting and the action of on the outside ot the hose softens it to such extent that when the Water is pumped through the system, the suction of the pump constricts the hose and shuts oil circulation.

When the hose is removed for any reason, it usually rendered useless from the necessity of prying it away from the pipes to which it is stuck by the shellac.

`The rubber hose requires constant renewal and e Acept when in perfect condition renders ineiucient service and is a source of danger to the Working of the system.

rl`he connection constructed in accordance 'with our inifention is adaptable to any cooling system and is possessed of the required flexibility, combined With durability, which renders it completely eihcient in operation.

We Will now proceed to describe our invention in connection with the accompanying drawings in which We have illustrated an embodiment of our invention as applied to the return line from the engine to the radiator oi a F ord automobile.

Figure l is a partial elevation of an engine and radiator showing the application of our invention.

2 is a horizontal sectional View of the device embodying our invention applied to a pair of pipes. Y1 Fig 3 is a cross-section on lines 3 3 of n rlhe pipe a extends from the under side of the rr 1-iator tank Z). rlhe pipe c is flanged and bolted t the cylinder head and coinniunicates with the Water jackets of the en- `gine (Z. rlhe adjustable radiator rod e extends from the dashboard f to the radiator g and acts to brace the radiator.

rEhe gland ZL having a flange e at one end is adapted to into pipe o. A second gland 9 provided with a. flange l; is adapted to fit into pipe c. The glands are provided With internal shoulders Z Z drilled for the reception orp a pin m adapted to prevent them from turning relatively to each other. The gland j is provided With a slot n for the reception of a pin o passed through pipe c by .vhich 'the gland is prevented from turning.

The outside faces of flanges k and e' are ed, respectively. A sleeve p internally threaded, half right hand and haltl left hand thread, is adapted to engage the threaded of glands 7L and j and when rotatec in one direction, draw them together, and when rotated in the opposite direction, separate them. llVash-ers Q, or any suitable packing material, are plac d between the ends of pipes (t and c and flanges z' and 7c. Packing nuts fr, suitably threaded, are engaged in the ends of sleeve p.

ln e gration, the glands are brought to- 'turning sleeve j) and the packing ed in the ends oic the sleeve. The

pipes o and c are inserted beands and the packing nuts. The

e adjusted to brace the radi- -ier position and the sleeve y) end the glands.

. V`.ding oi the glands causes a tight reen the Washers and the ends ot the P the glands adjusted the hitter 1; nuts are tightened up against the washers and a tight goint obtained.

"he glands cannot turn in the pipes in the operation of sleeve 2) due to the gland uhreaded with a right hand and a left hand n being secured to pipe c by slot n and pin o and to gland L by means ot pin m in shoulders Z, Z.

Although we have described our invention in connection with the cylinder head outlet connection et' a Ford car, it will be understood that itis equally adaptable to any other part or any other car.

Having now fully described our invention, what we claim and desire to protect by Letters Patent is:

l. Means for connecting the separated ends of water pipes in automobiles, comprising glands adapted to enter the respective pipes, and means adapted to separate said glands and effect a water-tight connection between them and their respective pipes.

Means tor eonnerting the separated ends ot water pipes in automobiles, comprising glands adapted to enter the respective pipes and having oppositely threaded peripheral portions, means holding said glands from turning relatively to the pipes, and a sleeve encircling the glands and threaded thereon, whereby the sleeve closes the opening between the glands and is turnable to separate the glands and torce them into water-tight connection with. their respective pipes.

3. Means for connecting the separated ends of water pipes in automobiles comprising glands, each gland having a portion adapted to enter its respective pipe and a portion outside such pipe and projecting in a radial direction beyond the periphery of the pipe, the projecting portions of the two glands having oppositely threaded peripheries, a sleeve surrounding the projecting portions of the glands and threaded thereon, washers interposed between the ends ol" the pipes and the projecting portions rse-7,22?

ot the respective glands, and packing nuts surrounding the respective pipes and sur rounded by and in threaded engagement with the sleeve.

d. ll/leans for connecting the separated ends of water pipes in automobiles comprising glands adapted to enter the respective pipes and having oppositely threaded peripheral portions, means connecting the glands comprising members slidable longitudinally one upon another but holding the glands from turning relatively to one another, means holding one gland Yfrom turning relatively to its respective pipe but permitting such gland to slide longitudinally', and a sleeve encircling both glands and having oppositely threaded portions engaging the oppositely threaded portions ot' the respective glands.

5. lt'leans adapted to form a water tight connection with a pipe comprising a gland adapted to engage a pipe, an exteriorly threaded flange on the gland, an internally threaded turnable sleeve surrounding and threaded on said flange, and means to prevent the gland turning with the sleeve.

6. yllhe combination with a pipe, of a gland adapted to enter the end o' the pipe, an exterior-ly threaded flange on the gland, a turnable sleeve threaded on said flange, means to prevent the gland from turning with the sleeve, a washer' between said flange and the pipe end, and a packin(Y nut threaded on the interior thread of the sleeve and extending between the sleeve and the pipe end. l I

In testimony ot which invention, we have hereunto set our hands, at Philadelphia, l'a. on this 8th day of December, 1919.
